Her Nov. 11 show at Toyota Center sold out Saturday in five minutes. Now the only way to get tickets is at inflated prices from ticket brokers or individuals.

Fifty-two ticket groupings were posted on eBay as of Monday afternoon. Depending on the seats' locations, bids ranged from $67 for a single seat to $1,275 for four seats. Most tickets on eBay averaged more than $200.

Brokers sell for just as much, if not more, being legally allowed to sell at any price the market will bear. They just aren't allowed to make such sales on the premises of an event.

For the lucky ones able to get tickets right way, their face value was economical for a tour, ranging from $25 to $65.

"The tickets are priced and sold as fairly as possible," said Debra Rathwell, senior vice president for AEG Live in New York, which is handling the tour.

"I can assure you this is no conspiracy," Rathwell said. "We do everything in our power to stop brokers from getting tickets, but it's impossible."

She said selling tickets at inflated prices has escalated in recent years because of the Internet. "That's changed everything."

Nor does it help that Hannah Montana is so popular. Rathwell said every show in every city, no matter how small, has sold out in minutes.

Such sellouts can prompt scheduling of extra shows, but in this case, that would be hard. Montana's Nov. 11 date in Houston will be followed by a Nov. 12 show in San Antonio, which also is sold out. She has a Nov. 9 show in Glendale, Ariz., but the next day should be needed to transport the stage and equipment — not to mention giving Cyrus, 14, a day off.

Last March, Houston's first Hannah Montana show set a new paid attendance record for the Houston Livestock Show & Rodeo, drawing of 73,295 fans to Reliant Stadium. That show sold out in three minutes. At Toyota Center, concert capacity is about 13,000.

"I've never seen counts like this," Rathwell said. "Usually some single seats remain available, but for this tour, they're all gone. It's sold out to the last seat."

Among parents dismayed by the fast Houston sellout and subsequent price gouging is Sandra Isget of Groveton. Having promised her 8-year-old son she'd get tickets, she wound up paying $629 for two seats to a Bossier City, La., show via Ticket Exchange, a service of Ticket Master, which allows fans to sell or buy among each other.

"I didn't trust eBay, because you don't know who those people are," Isget said.

Now she's having buyer's remorse.

"It was supposed to be something light-hearted and fun, and it's turned into something more expensive than our monthly mortgage," Isget said. "My son has no knowledge of us going into credit-card debt to get the tickets. I thought it would be worth it — that it would compensate for my own mental anguish — but it leaves me with such a bad feeling. I'd promised him. How far am I willing to go to keep that promise. If I refused, that only hurts him."

Denice Smajstrla of Pearland failed to get a ticket for her daughter Saturday but won't be paying scalpers.

"It's not the end of the world," she said. "It sounds like they (the promoter) were trying. I don't know that anyone is to blame. She's a popular little girl, and there's a lot of people."

Rathwell said promoters try to put as many tickets as possible into the hands of fans, not brokers. For Hannah Montana, sales were limited to four tickets per person, and half the tickets were sold through a fan-club promotion.

"We could be doing many more shows," she said of the tour. "I think it's hard when it's little kids and this show is like the only thing in their world, but what can you do?"

Hannah Montana mania began when her self-titled show debuted in March 2006. Its premise involves ordinary teen Miley Stewart, played by Miley Cyrus, who secretly transforms by night into pop sensation Hannah Montana.

Cyrus' father, country-music star Billy Ray Cyrus, plays her father and manager on the show and one of the few people who knows her double identity.

The series soon spun off into soundtrack albums and DVDs, and Cyrus, suddenly a pop star, launched her first tour last fall.

Her new tour begins Oct. 18 in St. Louis, Mo., and continues through Jan. 9 in Albany, N.Y. That will be followed by further production on the TV series.
